A thin and uniform manganese oxide layer was formed below 400 °C by thermal chemical vapor deposition (CVD) on a tetraethylorthosilicate (TEOS) oxide substrate. No Cu delamination were observed both in the as-deposited and in the annealed PVD-Cu/CVD-MnOx/TEOS samples deposited below 300 °C, meanwhile the Cu films were delaminated from the CVD-MnO x/TEOS substrates deposited at 400 °C. From the results of XPS, Raman and SIMS analysis, a major reason for degradation of the adhesion properties is considered to be amount of carbon inclusion in the CVD Mn oxide layer.
